Voicemail MP3 instead of WAV

How would I change the voicemail email attachment from WAV to MP3?

Google.

Thank you I will try that.

What if the system is using postfix?

I don’t have any experience with that and unfortunately I can’t research it for you at the moment.

If you are asking that because of the “sendmail -t” in that script Postfix has a sendmail executable which processes those commands…

Have a nice day!
